Stay or Leave

Hi, right now , right here, at this moment , I feel so confuse about my choice, I always priorities others than myself. But when I come this question, I asked myself "what if I get to know I have only 1 left day to live in this world? what is the thing that I've done and feel proud about myself? what is the thing that makes me regret? Do I feel happy and satisfy with my choice, my decision ,my life generally?"
Honestly, I'm not shocked at all when answers appeared in my mind, but what's my next move I asked myself. I'm afraid of changes. Fear & uncertainty hold me back from what I want to do. I'm afraid if I left this place, my friend will be having trouble, I know my role, I 've helped and done my part and even outside my job scope,even though I didn't get anything in return, I just want to help my colleagues, my friends ...what I know is, I do my best, contribute what I can, learn as much as I could, and the rest will come to me (benefit) 'someone told me this' ...(1/6/17) Jo.
to be continue... as maybe 1 day when I see back what I wrote today , I might have a different perception about my thought :)
